I have a Verizon LG-VK410 GPad 7.0 LTE. It is currently running Android version 5.0.2. I have rooted, but am not able to boot into recovery mode to install a custom rom(like one from CM). I have tried using the power button with volume down, release power button while still holding volume down when LG logo appears for a few seconds then hold volume down, up, and power button at same time combination. Sorry for the run on sentence! Multiple times and different combinations. I have tried using the following apps: Flashify, Quick Boot, Reboot. All of which failed! So I guess the next question is, am I stuck with Lollipop? Or can I put a custom rom of Marshmallow from CM? I am stunned.....I am really grateful for this site, and the people who take time to help people like me!!! Very awesome in todays world! Thank you XDA!
